I don't kn
Actually, I'm planning on redesigning gtree to be a part of larger ggraph
unit. As in the data structure theory, a tree is just a graph without cycle.
So I guess it should be made that way. There are a lot of graph and tree
variations though, so I think I need to take some time to design before

Answering to myself...
I believe the Graph types exist only in Lazarus LazControls package,
unit LvlGraphCtrl.

Thank you, Marco.
I was searching in stl package for a "Graph" type. is there such type?

Free only calls the destructor if self isn't nil.
procedure TObject.Free;
Hi,
gtree.TTree type has the following code:
constructor TTree.Create;
begin
FRoot := nil;
end;
destructor TTree.Destroy;
begin
FRoot.Free;
end;
How is possible then that the following program don't raise an error
when the destructor (via free) is called?
program Project1;
